...been ratified by the U.S. Senate. Nonetheless, as a top priority in its arms-control program, the Carter Administration has been pushing for a new, comprehensive test-ban agreement. Reason: it is fearful that the Russians, who have made far greater use of nuclear firepower than the U.S. for earth moving and other engineering purposes, could be gaining valuable military expertise in the process. Certainly the Soviets have shown interest in harnessing such detonations to a wide range of projects; their known tests have included the excavation of a half-mile-long canal trench in northern Russia...
Though scientists have established that the earth was born some 4.6 billion years ago, formed from debris orbiting the sun, they are less certain about when -and under what conditions-life began on the planet. Only last month, a Harvard University paleobiologist pushed back the dawn of life by announcing the finding of what appeared to be fossils of single-celled organisms dating back 3.5 billion years. Now biologists working under grants from NASA and the National Science Foundation have identified living creatures that may be little changed from organisms that lived during the first billion years of the earth...
...which gave rise to the "higher" forms of animals and plants, the other to the "lower" forms of bacteria. The identification of the archaebacteria's unique genetic structure suggests that there may be a third line of evolution. It also provides an important clue to the earth's early environment. Scientists have long believed that for about the first billion years after the formation of the earth, the atmosphere consisted largely of hydrogen, carbon dioxide and other gases, but virtually no free oxygen. The life-style and genetic structure of Woese's archaebacteria tend to support...
